Advanced Photonix ships 100G high-speed optical receivers

Picometrix LLC of Ann Arbor, MI, USA, a subsidiary of Advanced Photonix Inc (which designs and makes silicon, InP- and GaAs-based photodetectors, subsystems, and terahertz instrumentation), says that it is shipping its CR-100A high-speed 100G coherent optical receivers, which incorporate patented photodiodes and proprietary amplifiers and are suitable for DP-QPSK (dual-polarization quadrature phase shift keying) and alternative coherent modulation formats.

To meet demand from its global customer base, the firm began shipping pre-production 100G units this quarter (its fiscal first-quarter 2011) and has booked backlog of $1.2m for both the fiscal first and second quarters of 2011. It expects full Telcordia GR-468 qualification to be completed in fiscal Q2 (ending 1 October 2010), when the product will go into full production. The firm says that Telcordia qualification provides generic reliability assurance requirements for optoelectronic devices used in telecoms equipment, ensuring the reliable operation of optoelectronic devices and reducing life-cycle cost.

The suite of products are compliant with the compact coherent receiver multi-source agreement (CCRx MSA) announced at the European Conference and Exhibition on Optical Communication (ECOC 2009) in Vienna, Austria between Picometrix and u2t Photonics AG. The MSA defines an industry-standard, more cost-effective form factor for fiber-optic receivers optimized for coherent detection for both 40G and emerging 100G telecom systems. It is also consistent with the OIF (Optical Internetworking Forum) specification that the firm helped to develop over the past 18 months. The new CCRx package provides a standardized footprint, common pin-out and surface mount connections in a size-reduced package that aims to improve manufacturability for OEM system companies.

“The industry is moving forward into a 100G reality with the increased demand for voice, Internet, HDTV, and wireless that requires greater bandwidth and increased speed,” says Rob Risser, president & general manager of Picometrix and chief financial officer of API. "Next-generation wireline and wireless networks will require deployment of high-speed optical receivers to deliver this content, which is expected to grow annually by more than 25%. We are seeing robust demand for the 100G product and, as a result both our first and second fiscal quarter 2011, backlog is booked and we anticipate full production starting in our third fiscal quarter 2011, with demand still accelerating,” he adds.

“100G coherent receivers co-exist well with 40G direct modulation formats like DPSK and DQPSK,” continues Risser.
